Description

Technical Field

[0001] The utility model belongs to the technical field of dehydrators, and in particular relates to a fast dehydrator used for producing light stabilizers for marking paints. Background Art

[0002] Light stabilizer is an additive for polymer products. It can shield or absorb ultraviolet energy, quench singlet oxygen and decompose hydroperoxide into inactive substances. It can eliminate or slow down the possibility of photochemical reaction of polymer under light radiation, prevent or delay the process of photoaging, and thus extend the service life of polymer products.

[0003] In the process of producing light stabilizers, the solvent needs to be cooled to precipitate crystals, and then the crystals are filtered and dehydrated to obtain the light stabilizer. Therefore, the crystals containing excess water need to be dehydrated during use. However, existing dehydrators are often not convenient for recycling, and human intervention is required after each use, so the degree of automation is not high. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a rapid dehydrator for the production of light stabilizers for marking paints. The rapid dehydrator for the production of light stabilizers for marking paints can support and temporarily store the fallen crystals when the dehydration drum is not rotating through the coordinated arrangement of a tray and a dehydration drum. When the dehydration drum rotates, the tray can be driven to rotate synchronously, so that the crystals are thrown to both sides under the action of centrifugal force, and the excess water is thrown out of the dehydration drum. After the dehydration drum stops, the crystals can fall into the gap between the tray and the dehydration drum under the influence of gravity, and the dehydration and unloading are completed at the same time, and the next dehydration operation can be directly carried out.

[0006] Preferably, a supporting foot is fixedly installed on the bottom of the protective shell, and an anti-slip pad is fixedly connected to the bottom of the supporting foot.

[0007] Preferably, both sides of the inner wall of the slot are provided with limiting grooves, the inner wall of the slot is plugged with a drainage tube, and both sides of the outer surface of the drainage tube are fixedly connected with limiting blocks adapted to the limiting grooves.

[0008] Preferably, a drainage pipe is inserted below the outer surface of the protective shell, and the inner wall of the drainage groove is connected to the end of the drainage pipe.

[0009] Preferably, a main pulley is sleeved on the outer surface of the dehydration cylinder below the limiting ring, a motor is fixedly installed below the outer surface of the protective shell, the output end of the motor is connected to a secondary pulley through a key, and a transmission belt is wrapped around the outer surface of the secondary pulley and the outer surface of the main pulley.

[0010] Preferably, drainage holes are provided on the outer surface of the tray and the inner wall of the dehydration cylinder, and the inner wall of the tray and the outer surface of the dehydration cylinder are connected via the drainage holes.

[0011] The above technical solution has the following beneficial effects:

[0012] (1) The rapid dehydration machine for producing light stabilizers for road marking paint can support the crystals with the help of the tray after the crystals fall down through the coordinated arrangement of the dehydration cylinder and the tray, thereby being able to perform preliminary filtration of excess water. When the dehydration cylinder drives the tray to rotate synchronously, the crystals can be thrown out to both sides of the dehydration cylinder with the help of centrifugal force, so that the excess water is thrown out from the dehydration holes, thereby completing the dehydration operation. After the dehydration cylinder stops, the crystals will fall between the tray and the dehydration cylinder under the influence of gravity, and then fall downward, completing a single dehydration operation. Then, the undehydrated crystals can be re-sent, and the next dehydration cycle operation can be started, thereby improving the overall automation of the device, thereby improving the practicality of the device;

[0013] (2) The rapid dehydrating machine used for producing light stabilizers for marking paint can, through the setting of a protective shell, throw out excess water when the dehydrating cylinder rotates, and then make the water flow into the drainage trough, which is more convenient for drainage and discharge, thereby reducing the difficulty of operating the device.

Through the provision of the slot 3, the drainage tube 7 can be installed and positioned, and through the provision of the drainage groove 5, the separated water can be collected and drained, so as to be conveniently discharged from the drainage pipe 6;

[0023] Limiting grooves 4 are provided on both sides of the inner wall of the slot 3, and a drainage tube 7 is inserted into the inner wall of the slot 3. Limiting blocks 8 that are compatible with the limiting grooves 4 are fixedly connected on both sides of the outer surface of the drainage tube 7. Through the setting of the limiting grooves 4, they can cooperate with the limiting blocks 8 to ensure the stability of the drainage tube 7, and then use the drainage tube 7 to drain the crystals that need to be dehydrated, and the drainage tube 7 can also assist the rotation of the dehydration tube 9, thereby ensuring that the dehydration tube 9 reduces its own shaking when it rotates, and the end of the drainage tube 7 that penetrates the dehydration tube 9 is located above the tray 16, and then when the crystal falls, it can reduce the jumping of the crystal on the tray 16, thereby avoiding the situation where the crystal jumps on the tray 16 and bursts out, and when the dehydration tube 9 rotates, the crystal can be thrown out from the gap between the drainage tube 7 and the tray 16;
