Description

Technical Field

[0001] This utility model relates to the technical field of synthetic tanning agent production equipment, and in particular to a drying device for synthetic tanning agent production. Background Technology

[0002] Synthetic tanning agents are chemical substances prepared through chemical synthesis that can bind with collagen fibers in leather, thereby imparting specific properties (such as water resistance, flexibility, and stability) to the leather. They are not naturally occurring but are produced from raw materials such as phenol, naphthalene, and aromatic sulfonic acids through a series of chemical reactions including sulfonation, condensation, and neutralization. In leather production, synthetic tanning agents can be used alone or in combination with vegetable tanning agents to assist in tanning, adjust leather properties (such as color and feel), and improve production efficiency. They are particularly valuable when processing special leathers or meeting specific performance requirements.

[0003] Synthetic tanning agents play a crucial role in the leather manufacturing industry. The drying process directly affects product quality and production efficiency. Existing drying equipment for synthetic tanning agents has many shortcomings. In some traditional drying equipment, the drying method is relatively simple. Common hot air drying equipment relies solely on hot air blowing on the surface of the material to achieve drying. This method makes it difficult for the internal moisture of the material to migrate to the surface quickly, resulting in long drying time and low efficiency. Therefore, in order to address the above problems, a new drying equipment for synthetic tanning agents is proposed to solve these issues. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a drying equipment for the production of synthetic tanning agents, which can solve the technical problem that the existing drying methods are too simple and that it is difficult to dry synthetic tanning agents quickly by using only hot air, thus reducing the drying efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides a drying equipment for the production of synthetic tanning agents, adopting the following technical solution: It includes a drying chamber, a sealed cabinet door rotatably mounted on the front side of the drying chamber, and a PLC controller fixedly mounted on the outer wall of the sealed cabinet door. Two heating tubes are symmetrically mounted on the top inner side of the drying chamber, and a rotating structure is provided inside the drying chamber. The rotating structure includes a limiting plate fixedly mounted on the top of the drying chamber, a drive motor fixedly mounted on the upper end of the limiting plate, a drive gear fixedly connected to the output end of the drive motor, and a driven gear meshing with the outer wall of the drive gear. A rotating shaft is fixedly mounted in the middle of the driven gear, and three sets of drying trays are provided on the outer wall of the rotating shaft. Each drying tray has a stirring plate inside, and two fans are symmetrically arranged at the bottom of the drying chamber.

[0007] Optionally, both the driving gear and the driven gear are rotatably mounted on the upper end of the drying chamber, and a connecting sleeve is fixedly installed in the middle of each of the three drying trays and the connecting sleeve is fixedly connected to the outer wall of the rotating shaft.

[0008] Optionally, the bottom of the drying chamber is provided with multiple air inlets below the fan, a micro motor is fixedly installed at the bottom of the fan, and a protective cover is provided above the fan with its bottom fixedly installed at the bottom of the drying chamber.

[0009] Optionally, three positioning frames are fixedly installed on the inner wall of the drying oven, and a cylinder is fixedly installed above the positioning frames. One end of the cylinder is fixedly connected to a limit clamp, and the other end of the limit clamp is engaged with the stirring plate. The size of the stirring plate is adapted to the size of the drying tray.

[0010] Optionally, a temperature sensor is fixedly installed on the inner wall of the drying chamber, and multiple air outlets are symmetrically opened on the top of the drying chamber. The temperature sensor, heating tube, drive motor and cylinder are all electrically connected to the PLC controller.

[0011] Optionally, the drying oven is equipped with casters at each of the four corners of its bottom.

[0012] In summary, this utility model has at least one of the following beneficial effects: 1. By starting the drive motor, the drive motor drives the active gear to rotate, which in turn drives the driven gear to rotate, causing the three-layer drying trays on the rotating shaft to start rotating. At the same time, the fan and heating tube are started. The fan blows cold air from the outside into the drying chamber. After being heated by the heating tube, the cold air comes into contact with the material and begins to dry it. The piston rod of the cylinder extends and retracts, causing the stirring plate on the limit clamp to rise and fall. The stirring plate stirs the material on the drying tray, allowing the material to fully contact the hot air. Through the rotation of the multi-layer drying trays and the rising and falling of the cylinder driving the stirring plate to stir the material, the material can fully contact the hot air, accelerating the migration of moisture inside the material, greatly shortening the drying time and improving the drying efficiency.

[0013] Meanwhile, the rotation of the drying tray avoids the problem of material accumulation and clumping. The cylinder drives the stirring plate to turn the material over so that all parts are heated evenly, effectively solving the problem of uneven drying in existing equipment, improving the stability of product quality and the uniformity of material drying.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] The following is in conjunction with the appendix Figure 1—5. This utility model will be described in further detail.

[0019] Reference Figure 1-5 In this embodiment, in order to solve the technical problem that the existing drying method is too simple and the drying efficiency is reduced by using only hot air to dry synthetic tanning agents, this utility model discloses a drying equipment for the production of synthetic tanning agents; The equipment includes a drying oven 1, a sealed cabinet door 2 rotatably mounted on the front side of the drying oven 1, and a PLC controller 3 fixedly mounted on the outer wall of the sealed cabinet door 2. Two heating tubes 10 are symmetrically mounted on the top of the inner side of the drying oven 1, and a rotating structure 4 is provided inside the drying oven 1. The rotating structure 4 includes a limiting plate 41 fixedly mounted on the top of the drying oven 1. A drive motor 42 is fixedly mounted on the upper end of the limiting plate 41. A drive gear 43 is fixedly connected to the output end of the drive motor 42, and a driven gear 44 is meshed with the outer wall of the drive gear 43. A rotating shaft 45 is fixedly mounted in the middle of the driven gear 44. Three sets of drying trays 46 are provided on the outer wall of the rotating shaft 45. Each drying tray 46 is provided with a stirring plate 83. Two fans 92 are symmetrically arranged at the bottom of the drying oven 1. Specifically, the driving gear 43 and the driven gear 44 are both rotatably mounted on the upper end of the drying chamber 1, and the three drying trays 46 are all fixedly mounted with connecting sleeves 47 in the middle, and the connecting sleeves 47 are fixedly connected to the outer wall of the rotating shaft 45.

[0020] The drive motor 42 drives the active gear 43 to mesh with the driven gear 44 to rotate, which facilitates the stable rotation of the three sets of drying trays 46 on the rotating shaft 45. The position of the material in the tray is adjusted by rotation, so that the synthetic tanning agent material on the tray can be heated evenly and the material can be prevented from accumulating and clumping. Specifically, the bottom of the drying oven 1 is provided with multiple air inlets 93 located below the fan 92. A micro motor 91 is fixedly installed at the bottom of the fan 92, and a protective cover 9 is provided above the fan 92, with the bottom of the protective cover 9 fixedly installed at the bottom of the drying oven 1.

[0021] When the fan 92 rotates, the air inlet 93 allows cold air from the outside to enter smoothly. This cold air is heated by the heating tube 10 to form hot air, which comes into contact with the synthetic tanning agent material on the drying tray 46 to dry the material. The protective cover 9 is designed to protect the fan 92. Specifically, three positioning frames 8 are fixedly installed on the inner wall of the drying oven 1, and a cylinder 81 is fixedly installed above the positioning frame 8. One end of the cylinder 81 is fixedly connected to a limit clamp 82, and the other end of the limit clamp 82 is engaged with the stirring plate 83. The size of the stirring plate 83 is adapted to the size of the drying tray 46.

[0022] By extending and retracting the piston rod of cylinder 81, the stirring plate 83 on the limit clamp 82 is raised and lowered, thereby stirring and turning the material on the drying tray 46, so that the material can fully contact the hot air, accelerate the drying process, and ensure that the material is dried evenly. Specifically, a temperature sensor 7 is fixedly installed on the inner wall of the drying chamber 1, and multiple air outlets 5 are symmetrically opened on the top of the drying chamber 1. The temperature sensor 7, heating tube 10, drive motor 42 and cylinder 81 are all electrically connected to the PLC controller 3.

[0023] When the temperature sensor 7 detects that the temperature inside the drying chamber 1 is lower than the set temperature, the PLC controller 3 controls the heating tube 10 to increase its power and the fan 92 to increase its speed, thereby increasing the temperature and hot air flow inside the drying chamber 1. When the temperature sensor 7 detects that the temperature inside the drying chamber 1 is higher than the set temperature, the controller controls the heating tube 10 to decrease its power and the fan 92 to decrease its speed, so that the temperature inside the drying chamber 1 is kept within the set range, thereby achieving precise control of the drying temperature. The existing technology is mature and widely used. An air outlet 5 is provided on the top of the drying chamber 1 to exhaust the hot and humid air generated during the drying process.

[0024] Specifically, the four corners of the bottom of the drying oven 1 are all equipped with casters 6.

[0025] Universal casters 6 are installed at the bottom of the drying box 1, so that when the drying box 1 needs to be moved, the foot brake can be released and the universal casters 6 can be used to move it, which facilitates the convenient movement of the drying box 1 and reduces the burden on the staff.

[0026] The specific working principle is as follows: The drying chamber 1 is installed in a suitable position according to the design requirements, ensuring its stability. The internal temperature parameters of the drying chamber 1 are preset on the PLC controller 3. The sealed cabinet door 2 is opened, and the synthetic tanning agent material to be dried is conveyed to each drying tray 46. At this time, the drive motor 42 is started, driving the drive gear 43 to rotate. The drive gear 43 drives the driven gear 44 to rotate, causing each drying tray 46 on the rotating shaft 45 to begin rotating. This facilitates the adjustment of the position of the synthetic tanning agent material for uniform drying. Simultaneously, the fan 92 and heating tube 10 are started. The fan 92 blows cold air from outside into the drying chamber 1. After being heated by the heating tube 10, the cold air comes into contact with the material, beginning the drying process. During the drying process, the cylinder 81 above the positioning frame 8 is activated. The piston rod of the cylinder 81 extends and retracts, causing the stirring plate 83 on the limit clamp 82 to rise and fall. The stirring plate 83 stirs the material on the drying tray 46, ensuring that the material comes into full contact with the hot air. The temperature sensor 7 monitors the temperature inside the drying chamber 1 in real time and transmits the temperature signal to the PLC controller 3. The controller adjusts the power of the heating tube 10 and the speed of the fan 92 according to the difference between the set temperature and the actual temperature, so that the temperature inside the drying chamber 1 is maintained within the set range. When the material is dried, the operation of the drive motor 42, the fan 92, and the heating tube 10 is stopped, and then the operator can take out the dried material.
