Technical Field

[0001] The utility model relates to the technical field of plasticizer production, in particular to a solvent recovery device for plasticizer production. Background Technique

[0002] The rubber plasticizer is applicable to the plastic refining of natural rubber and synthetic rubber. Using this plasticizer can improve the plasticity and plastic refining efficiency of rubber, shorten the plastic refining time by about one-third, save energy and improve labor productivity. It is an ideal high-efficiency and energy-saving rubber processing aid, suitable for plastic refining at higher and lower temperatures, and can be used on open mills and internal mixers. At present, the solvent needs to be recovered during the production of the environmentally friendly plasticizer, but the existing solvent recovery devices have low practicability, cannot filter and stir the solvent. The lack of filtration results in a large amount of impurities in the solvent, affecting the reuse of the solvent. The lack of a stirring function leads to precipitation of the solvent, which is not conducive to use.

[0003] The utility model with the publication number CN212680750U proposes a solvent recovery device during the production of an environmentally friendly plasticizer, including a recovery tank. A bottom plate is arranged at the bottom of the recovery tank. A bracket is fixedly connected between the top of the bottom plate and the recovery tank. A motor is fixedly connected to the bottom of the recovery tank. The top of the output end of the motor is fixedly connected with a rotating rod. The top of the rotating rod penetrates into the inner cavity of the recovery tank. Stirring rods are fixedly connected to the top of both sides of the rotating rod. By setting the recovery tank, bottom plate, bracket, motor, rotating rod, stirring rod, water pump, connecting pipe, feeding pipe, pipe cover, limiting plate, filter plate, control box, pulling plate, inserting block, inserting slot, pulling rod, spring, pulling ring, clamping plate and clamping slot, the utility model solves the problem of low practicability of the existing solvent recovery device during the production of the environmentally friendly plasticizer. The solvent recovery device during the production of the environmentally friendly plasticizer has the advantage of high practicability and is worthy of promotion.

[0004] However, the above-mentioned existing technology still has the following deficiencies when in use: 1. After impurities accumulate on the filter plate, it will affect the flow rate of solvent filtration, thereby affecting the filtration efficiency. To solve this problem, the filter plate usually needs to be disassembled and assembled frequently, which is time-consuming and laborious; 2. In order to avoid the problem that the filtered solvent in the recovery tank precipitates and affects subsequent use, a circulating water pump and a stirring structure are set up, which not only have a complex structure, but also require a large cost investment and are not convenient for later maintenance.

[0005] Therefore, the utility model provides a solvent recovery device for plasticizer production. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a solvent recovery device for producing peptizer, including a recovery tank 1. A feed pipe 11 is arranged at the top of the recovery tank 1. The feed pipe 11 is a channel for feeding the solvent to be filtered.

[0023] In this technical solution, a filter cylinder 2 is arranged inside the feed pipe 11. The peripheral wall of the filter cylinder 2 is the filtering part. A detachable sedimentation filter cylinder 3 is arranged inside the filter cylinder 2. Preferably, during specific implementation, a support platform 111 is fixedly arranged on the inner peripheral wall of the feed pipe 11. An outer support ring 21 is fixedly sleeved outside the top of the filter cylinder 2. The support ring 21 is placed on the support platform 111. A limit bolt 112 whose one end is located above the support ring 21 is screwed through the outer peripheral wall of the feed pipe 11. The limit bolt 112 limits the support ring 21. When the limit bolt 112 is loosened, there is no restricting object above the support ring 21. At this time, the filter cylinder 2 can be easily removed. The function of the sedimentation filter cylinder 3 is to collect the impurities filtered in the filter cylinder 2 and reduce the speed of blockage formation. An outer edge in sealed connection with the inner peripheral wall of the filter cylinder 2 is fixedly connected to the mouth of the sedimentation filter cylinder 3. The function of the scraping ring 4 is to scrape the impurities attached to the inner wall of the filter cylinder 2 and clean the blockage on the inner wall of the filter cylinder 2 to ensure the filtering flow rate of the filter cylinder 2. Among them, the sedimentation filter cylinder 3 and the recovery box 1 are connected in a sliding fit in the up and down direction. That is to say, when the sedimentation filter cylinder 3 moves up and down, it can drive the scraping ring 4 to perform scraping actions.

[0024] A cover 5 is detachably connected to the top of the feed pipe 11. The cover 5 and the feed pipe 11 can be connected by a screwing connection method for the purpose of blocking the feed pipe 11.

[0025] In this embodiment, a transmission shaft 31 is screwed to the bottom of the sedimentation filter cylinder 3. During specific implementation, a threaded pipe can be welded to the bottom outside the sedimentation filter cylinder 3, and then threads for screwing connection with the threaded pipe are provided on the outer peripheral wall of the transmission shaft 31. Among them, a support plate 41 is welded between the scraping rings 4. The function of the support plate 41 is to facilitate manual removal of the sedimentation filter cylinder 3 by twisting the support plate 41. The bottom of the transmission shaft 31 penetrates through the bottom of the recovery box 1 and the two are in sealed sliding connection. When the transmission shaft 31 moves up and down, it can drive the sedimentation filter cylinder 3 to move up and down. During specific implementation, a guide sleeve can be welded to the bottom of the recovery box 1. The transmission shaft 31 passes through the guide sleeve, and then a sealing rubber sleeve is arranged between the guide sleeve and the transmission shaft 31.

[0026] Furthermore, a reciprocating lead screw 6 is rotatably connected to the bottom outside the recovery box 1 through a bracket. A transmission nut 7 is screwed on the reciprocating lead screw 6. The bottom of the transmission shaft 31 is fixedly connected to the outer wall of the transmission nut 7. When the reciprocating lead screw 6 rotates, it can drive the transmission nut 7 to move up and down, and further drive the transmission shaft 31 to move up and down. During use, a control motor whose output shaft is fixedly connected to the bottom of the reciprocating lead screw 6 is installed at the bottom of the bracket to provide driving force for the rotation of the reciprocating lead screw 6.

[0027] In this embodiment, a stirring plate 311 is fixedly connected to the outer peripheral wall of the transmission shaft 31. When the transmission shaft 31 moves up and down, it will drive the stirring plate 311 to move up and down. The stirring plate 311 will stir the solvent up and down, which can effectively prevent precipitation. This integrated setting for anti-precipitation and anti-blockage greatly simplifies the structure of this device.

[0028] In this embodiment, a necking tube 32 is provided at the top of the sedimentation filter cartridge 3. A horn tube 321 is fixedly provided at the top of the necking tube 32. The large end of the horn tube 321 is fixedly connected to the bottom of the scraping ring 4. The setting of the necking tube 32 helps the impurities in the filter cartridge 2 to settle into the sedimentation filter cartridge 3, and can prevent the impurities in the sedimentation filter cartridge 3 from rising upward, improving the reliability of impurity sedimentation.

[0029] Working principle: During recovery, the solvent to be filtered is injected into the feed pipe 11. After being filtered by the filter cartridge 2, the solvent enters the recovery tank 1 to achieve the recovery of the solvent. When using the filtered solvent, just open the discharge valve at the bottom of the recovery tank 1. During the filtering process, when the filter cartridge 2 is blocked, control the reciprocating lead screw 6 to rotate, and the transmission nut 7 moves up and down to drive the transmission shaft 31 to move up and down. At this time, the scraping ring 4 will move up and down to scrape the impurities on the inner wall of the filter cartridge 2. At this time, the solvent to be recovered can smoothly pass through the filter cartridge 2 to achieve normal filtering function. The impurities scraped off from the filter cartridge 2 will settle into the sedimentation filter cartridge 3 along with part of the solvent. After the solvent in the sedimentation filter cartridge 3 is discharged, the impurities will accumulate in the sedimentation filter cartridge 3. During the up and down movement of the transmission shaft 31, the stirring plate 311 will stir the filtered solvent up and down, which can effectively prevent precipitation.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
