Description

Technical Field

[0001] This utility model relates to the field of rubber accelerator purification and drying technology, specifically a rubber accelerator purification and drying device. Background Technology

[0002] Rubber accelerators refer to rubber vulcanization accelerators, usually in solid form. Rubber vulcanization mainly uses sulfur, but the reaction between sulfur and rubber is very slow, hence the development of vulcanization accelerators. After the synthesis reaction is complete, the crude product usually contains unreacted raw materials, solvents, catalyst residues, and impurities such as moisture, requiring purification and drying to obtain a qualified finished product.

[0003] According to application number CN202121321141.5, an all-around dryer for the production and processing of rubber accelerators is disclosed, including a base, a drive mechanism fixedly installed on both sides of the upper end face of the base, and a drying mechanism fixedly installed at the center of the upper end face of the base.

[0004] The rubber accelerator in the above case only has a single drying effect, which means that the purification and drying of the rubber accelerator need to be handled separately. This requires the material to be transferred between different equipment, which increases the number of operation steps and time, reduces the ability to carry out continuous production, and during the transfer process, the wet material before drying may reabsorb moisture from the air, causing it to be contaminated again and affecting the drying quality. Therefore, we provide a rubber accelerator purification and drying device. Utility Model Content

[0021] 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.

[0022] Please see Figure 1-4 A rubber accelerator purification and drying device includes a housing 1 made of 316 stainless steel. A feeding cover is provided on the rear side of the top of the housing 1. The feeding cover can be opened by pulling upwards to facilitate the addition of rubber accelerator and cleaning liquid into the housing 1. A transparent observation window is provided at the bottom of the front of the housing 1 to facilitate observation of the internal condition of the housing 1. A controller is provided at the top of the front of the housing 1. The controller receives signals from the temperature sensor 24 and controls the power of the heating plate 23, the stirring motor 22, the servo motor 31, and the rotary motor 35 to start and stop, thereby realizing the control of the automated process. An exhaust pipe is installed on the top right side of the housing 1 and is connected to it to discharge the water vapor generated during the drying process, reduce the humidity inside the housing 1, and accelerate the drying of the material. A valve is provided on the exhaust pipe. A drain pipe is installed on the bottom right side of the housing 1 and is connected to it.

[0023] The interior of the housing 1 houses a cleaning and drying assembly 2, which includes a guide hopper 21, a stirring motor 22, a heating plate 23, and a temperature sensor 24. The guide hopper 21 is installed on the inner wall of the housing 1 and carries the rubber accelerator. It serves as a shared space for washing, purification, heating, and drying. The arc-shaped inner wall guides the material to flow towards the bottom opening while preventing washing liquid residue. It is made of 316 stainless steel and is fixedly connected to the inner wall of the housing 1 by welding. The stirring motor 22 is installed on the top of the housing 1. The bottom end of the output shaft of the stirring motor 22 penetrates the housing 1 and extends into it, where a stirring rod 25 adapted to the guide hopper 21 is installed. The bottom of the stirring rod 25... The end of the guide bucket 21 extends into its interior. The stirring motor 22 drives the stirring rod 25 to rotate. During the washing stage, the material is fully in contact with the washing liquid. During the drying stage, the material is turned over to ensure uniform heating. There are two heating plates 23, which are respectively installed on the left and right sides of the top of the inner wall of the shell 1. The heating plates 23 transfer heat to the shell 1 through electric heating to provide a heat source for material drying. The temperature sensor 24 is installed on the left side of the inner wall of the shell 1 and above the guide bucket 21. The temperature sensor 24 monitors the drying temperature inside the shell 1 in real time and feeds the signal back to the controller. When the temperature exceeds the set value, the controller automatically reduces the power of the heating plate 23, and increases the power when it is below the set value.

[0024] A drive adjustment assembly 3 is provided on the housing 1. The drive adjustment assembly 3 includes a servo motor 31 and a mounting block 32. The servo motor 31 is mounted on the right side of the housing 1, and the mounting block 32 is mounted on the right side of the guide bucket 21 and corresponds to the position of the servo motor 31. The servo motor 31 drives the threaded rod 33 to rotate in both directions, so that the rotational motion of the threaded rod 33 is converted into the linear motion of the adjustment block 34, adjusting the horizontal position of the annular baffle 36 and controlling the docking accuracy between the annular baffle 36 and the bottom opening of the guide bucket 21 to avoid material leakage or misalignment. The servo motor 31 has a self-locking function, which can lock the position of the adjustment block 34 after stopping to prevent vibration from causing displacement. The left end of the output shaft of the servo motor 31 passes through the housing 1 and extends into it. A threaded rod 33 is installed on the part of the mounting block 32. A bearing is installed in the groove on the right side of the mounting block 32. The inner ring of the bearing is rotatably connected to the surface of the threaded rod 33. The bearing supports the left end of the threaded rod 33, reducing the radial wobble of the threaded rod 33 during rotation. An adjusting block 34 is threadedly connected to the surface of the threaded rod 33. The adjusting block 34 transmits the linear motion of the threaded rod 33 and provides stable support for the rotary motor 35. The rotary motor 35 is installed at the bottom of the adjusting block 34. The rotary motor 35 drives the annular baffle 36 to rotate slowly, switching the position of the through groove 37. During the washing stage, the annular baffle 36 is aligned with the opening at the bottom of the guide bucket 21 to seal it. After washing, the through groove 37 is aligned with the bottom of the guide bucket 21. An opening allows liquid to drain and then dry. After drying, the servo motor 31 drives the annular baffle 36 to separate from the guide hopper 21, allowing the material to be discharged into the collection shell 42. An annular baffle 36, which mates with the bottom opening of the guide hopper 21, is installed at the bottom of the output shaft of the rotary motor 35. The bottom of the annular baffle 36 is in close contact with the bottom of the guide hopper 21. A through groove 37, matching the bottom opening of the guide hopper 21, is provided on the right side of the top of the annular baffle 36. When the through groove 37 is aligned with the guide hopper 21, washing wastewater is discharged through the through groove 37. When the through groove 37 is misaligned, it blocks the bottom of the guide hopper 21, achieving temporary storage of the material within the guide hopper 21. The annular baffle 36 is made of 316 stainless steel. Made of stainless steel, the inner wall of the through channel 37 is equipped with a screen 38. The screen 38 filters rubber accelerator particles in the wastewater during the washing stage. The screen 38 is made of 316L stainless steel woven mesh with a mesh size of 80-120. The bottom of the annular baffle 36 is equipped with a guide pipe 39 that communicates with the through channel 37. The guide pipe 39 guides the washing wastewater to the right side of the partition 41 to prevent the wastewater from flowing into the collection shell 42. A positioning rod 5 is installed on the right side of the mounting block 32. The right end of the positioning rod 5 passes through the adjusting block 34 and extends to its outside, where it is fixedly connected to the right side of the inner wall of the shell 1. By setting the positioning rod 5, the stability of the left and right movement of the adjusting block 34 is improved, and the adjusting block 34 is restricted to moving only in a straight line.

[0025] The housing 1 is equipped with a collection component 4, which includes a partition 41. The partition 41 is installed at the bottom of the inner wall of the housing 1 and is fixedly connected to the inner wall of the housing 1 by welding. The partition 41 divides the bottom space of the housing 1 into a finished product collection area on the left and a wastewater discharge area on the right. A collection shell 42 is provided on the left side of the partition 41. The collection shell 42 is used to collect the purified and dried rubber accelerator. The collection shell 42 is made of 316 stainless steel. The side of the collection shell 42 near the partition 41 is in contact with the partition 41, and the side of the collection shell 42 near the inner wall of the housing 1 is in contact with the inner wall of the housing 1. A pull plate 43 is installed on the left side of the collection shell 42. The left side of the pull plate 43 penetrates the housing 1 and extends to its outside. The pull plate 43 is used to pull the handle of the collection shell 42 to facilitate the operation of the collection shell 42.

[0026] In use, open the feeding cover and pour the crude rubber accelerator and detergent or water into the guide hopper 21 inside the housing 1. Then start the stirring motor 22. The stirring motor 22 drives the stirring rod 25 to rotate through the output shaft. When rotating, it can fully turn the material and make the material evenly contact the washing liquid, thereby cleaning and purifying the rubber accelerator. After cleaning, start the rotating motor 35, which drives the annular baffle 36 to rotate slowly by 180 degrees. When the through groove 37 is completely aligned with the bottom opening of the guide hopper 21, the rotating motor 35 will stop automatically. The washing wastewater carrying impurities passes through the screen 38, which filters out the wastewater. The wastewater flows into the right side of the partition 41 through the guide pipe 39 and is discharged through the drain pipe. When no wastewater flows out of the drain pipe, the drying operation can be carried out.

[0027] The heating plate 23 is activated, and the temperature sensor 24 monitors the temperature inside the shell 1 in real time. At the same time, the stirring motor 22 continuously drives the stirring rod 25 to rotate, so that the material can be heated evenly. When it is time to discharge the material after heating is completed;

[0028] Start the servo motor 31. The servo motor 31 drives the adjusting block 34 to move horizontally to the right along the positioning rod 5 through the threaded rod 33. Simultaneously, it drives the rotary motor 35 and the annular baffle 36 to move to the right. When the annular baffle 36 is completely separated from the bottom opening of the guide hopper 21, the material in the guide hopper 21 falls into the collection shell 42 for collection. After collection is completed, pull the pull plate 43 to the left to pull the collection shell 42 out of the shell 1.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
